Percentage of migraine attacks achieving (A) pain relief and sustained pain relief and (B) pain freedom and sustained pain freedom (full analysis set). For pain relief, percentages are based on the total number of attacks treated when pain was moderate or severe. Pain relief = pain level reduced to none or mild. Sustained pain relief = pain level reduced to none or mild with no worsening of headache, second dose of study drug, or use of rescue medication over 24 hours or 48 hours after the attack. Pain freedom = pain level reduced to none (grade 0). Sustained pain freedom = grade 0 from 120 minutes to over 24 hours, and 48 hours after the initial dose with no recurrence of headache, or rescue medication/second dose up to 24 and 48 hours. Odds ratios (OR) are based on the fitted generalized estimating equations models.*P < .05, **P < .01, ***P < .001.
